摘　　要：以塔里木盆地东河塘组为研究对象,通过大量野外剖面观测、钻井岩心观察,研究了东河塘组层序划分和特征,共划分4个(SQ1、SQ2、SQ3、SQ4)3级层序,论述了不同层序在不同地区层序内体系域的构成特征;研究了层序对比,得出各层序在不同地层分区发育程度不同。为了能更好地揭示东河塘组层序的发育、展布规律,分别建立了东西和南北向的层序地层格架模型。Based on lots of observation of outcrops, cores and well logs, the Donghetang Formation was divided into four III-grade sequences, SQ1, SQ2, SQ3 and SQ4. The different constitutions of system tracts of different sequences in different areas were discussed, the sequence contrast was studied, from which the different development degree among sequences in different stratigraphic areas can be find. In order to reflect the development and distributing rules of the sequences of Donghetang Formation, the sequence stratigraphic framework models of W-E and N-S direction were set up.
